Edinburgh Castle, City of Edinburgh

Perhaps the most famous (and most visited) castle in Scotland is right in the center of the capital city. Perched on top of the city on Castle Rock, this fortress has a strong presence in Edinburgh's skyline. The oldest section of the castle dates to the 12th century, and many visitors travel here specifically to see the Crown Jewels of Scotland. Guided tours are available.

Culzean Castle, Ayrshire

Observant travelers might recognize Culzean Castle from the back of the 5-pound note issued by the Royal Bank of Scotland. This cliffside castle on the Ayrshire coast has been associated with the Kennedy family for centuries. It is a particularly memorable example of a fairy tale-like structure with its turrets and battlements, stationed above the stormy seas and surrounded by gardens and forests.

Ballindalloch Castle, Banffshire

Often called "The Pearl of the North," this 16th-century castle is in the heart of one of Scotland's whisky regions, Speyside. Unlike other castles in Scotland, this is one of the few castles in the country that remains private: The Macpherson-Grant family has continually lived here over the centuries. The castle is open to visitors during the summer months and has a shop with a variety of Scottish goods including tartans and jewelry.

Movie buffs might recognize Castle Fraser from "The Queen," starring Helen Mirren (it appeared as a backdrop). Castle Fraser is one of the grandest, most romantic-looking castles in the country. Built between 1575 and 1636, the castle sits on more than 300 acres of landscaped grounds and woodlands. Inside, it has the feeling of a family home with portraits of the Fraser family and original furniture.

Stirling Castle, Stirlingshire

One of the largest (and most important from a historic/architectural perspective) castles is Stirling Castle. An easy trip from both Edinburgh and Glasgow, this castle was once the destination of knights and nobles who flocked to the luxurious property with its elaborate gardens. It's a good spot for families to visit; costumed characters in historic roles are on the grounds, and children can dress up in period costumes and play medieval instruments.

The mythical Loch Ness Monster, Nessie, might lure travelers to the Scottish Highlands, but it is Urquhart Castle that delivers the drama. One of the most-visited castles in the country, this castle's Grand Tower overlooks expansive Loch Ness. An early medieval fortification was built here, but the ruins seen today date to the 13th to 16th centuries. The castle also played a strategic role in the Wars of Scottish Independence.

Glamis Castle, Angus

One of the most towering -- and historically interesting -- castles in Scotland is Glamis Castle. This structure has the claim to fame as being the setting for Shakespeare's "Macbeth," along with being the childhood home of Queen Elizabeth, the Queen Mother (her younger daughter, Princess Margaret, was born here). The surrounding estate is made up of 14,000 acres of gardens, farms and forests.

Inveraray Castle, Argyllshire

Located in western Scotland on the shore of Loch Fyne, this castle has a fairytale facade with an enchanting interior. Many visitors indulge in the tea room here, offering a glimpse into royal life.

Crathes Castle, Aberdeenshire

Found in the Aberdeenshire woodlands, Crathes Castle dates to the 16th century and has ties to Scottish warrior-king Robert the Bruce.

Travelers interested in art will be drawn to the collection of portraits and painted ceilings.
